Keep meaning to get myself a copy of the OSG, and someone's just offered
me the 7th ed - that's the 7th edition of the guide to the 16th edition
regs - all very confusing!

The OSG doesn't have an edition no. as such, so be careful. The current
edition has a brown cover and was last revised in 2004 to incorporate
the change in wiring colours. The one before that was blue. What
colour is the one you've being offered?

The OSG was last "revised" in April 2006 but as far as I can tell the
only change was the IET reference on the rear cover.
